If anyone else comes across this thread looking for the correct lanyard, I found the part number on "2002 Sea Doo Islandia, 5709 - Electrical Accessories 1" exploded view. It's part number 278001431 and it matches all the eBay ones that state it's for "All 1995 models and prior and all 1996 & 1997 models WITHOUT D.E.S.S.", however it is correct for the 2002 Isladia and all other years that use the same kill switch.
